# Use for $call_verb

    I just thought of a really cool thing that could be done if there existed a
    server->database interface for calling verbs.

    The idea would be that a verb call: foo:bar(args) would attempt to call
    #0:call_verb(foo, "bar", {@args}) before making the call by itself.  If the
    verb on #0 did not exist (or was -x), it would proceed with the call normally,
    if the the built-in raised an error, that would be passed on to the calling
    program, otherwise, the server would pass back whatever call_verb returned to
    the caller.

    If NO type checking were done in advance of call_verb, it would be possible to
    do something like this:

    {2,1,4,3}:sort();

    This would call $call_verb({2, 1, 4, 3}, "sort", {}), which would call
    $list_utils:sort({2, 1, 4, 3}), which returns {1,2,3,4} to $call_verb, which
    passes that back to the player.  This seems like a very cool thing to do,
    OOP-wise.
